Carrière de la Vallée Heureuse
Business Partner and Geosite Manager
Carrière de la Vallée Heureuse – Official Partner of the Cross-Channel Geopark
Located at the heart of the Geopark, Carrière de la Vallée Heureuse works a major deposit of Carboniferous limestone, formed in marine environments over 300 million years ago. The site is both an active quarry and an important geological observation site, contributing to the understanding and appreciation of local natural heritage.
As a committed partner of the Cross-Channel Geopark, the quarry is developing an approach that balances economic activity with environmental responsibility and public engagement. This partnership is reflected through educational and interpretation activities, the hosting of school and professional groups, and the sharing of scientific knowledge about the geological history of the site.
The company also implements practices aimed at reducing its environmental footprint, including responsible resource management, minimising disturbance, progressive restoration of worked areas, and careful landscape integration.
Through its subsidiary CVH Pierre Naturelle, the company extracts and processes two ornamental stone resources — Lunel marble and Marquise stone — helping to preserve traditional know-how and support the conservation of regional and national built heritage.
Carrière de la Vallée Heureuse demonstrates that an active quarry can also be a place for discovery, learning and the promotion of geological heritage, fully aligned with the sustainable development objectives of the Cross-Channel Geopark.
